Being confronted with our own biases is a humbling experience. I hate to admit it, but for most of my life, even when I was in college, the images I had of scientists and engineers were typically of men. Growing up, the parochial school I attended taught us that men are supposed to be providers and women are supposed to be nurturers. According to my teachers and pastors, men are more logical and women are more emotional; therefore, men are more reliable for leadership roles. Popular culture at that time, which is unfortunately not very different from today’s, was full of references to dumb blonde women, women’s “excuse to be crazy” once a month, and men’s mistrust of “anything that bleeds for seven days and doesn’t die.”
